PATENT WILLIAM w. AKER; on SAN FRANCISCO, CALIFORNIA, ASSIGNOR 1T0AMEIZIGAN cA COMPA NY, OF NEW YORK, N. Y.', A. CORPORATION OF NEW JERSEYSHEET METAL CONTAINER 7 Application filed ma 8,1931. Serial No. 536,009.

The present invention relates to a sheet metal container and has'for itsobject broadly the provision of an improved container ,structure of thetype wherein'an external friction 5 or slip cover is provided to closedown over" the upper open end of the container.

An important object of the invention is I the provision of a containerof this character, the parts of which will be so constructed andarranged that a relatively more rigid slip or frictional engagement maybe pro vided between the closing snrfacesf Another important object ofthe invention is the provision of a container of the character vabovementioned, the parts'of which may be so constructed and arranged as topermit,

the employment of a. gasket or sealing material into which the lowermostportions of the cover flange may seat or engage, so that the containermay be sealed by-the cover independently of the tightness of fit betweenthe inter-en gaging container and cover parts; A furtherimportant objectof the inven-.

, tion is the reinforcement ofthe mouth or top of the container body forexternal frictional l engagement by the coverand without substantialobstruction of the opening into or month of the container body.

' Another important object of the inven-- tion is the provision of newand improved bail attaching means for a sheet-metal 0on tainer, theinvention contemplating. 1n thisregard the provision of a contalner ofH141 creased rigidity and stiffness at the top of its bodv and increasedrigidity to the partin which the bail ends are attached. a V

A still furtherimportant object of the invention is the provision in acontain er ofthe 0 character described of animprovedconstruc tionfacilitating the prying off of 'the cover from the body. 7

Numerous other objects of the invention .will beapparent as 'it"isibetterlunderstood from the following description; which, taken inconnection with the accompanying draw,-

The present invention contemplates an improved form of containerwhichhas substan tially a full opening that is reinforced by anannuluswhich' provides a smooth friction seatfor an'external frictionclosure oflthe slip cover-type and which alsoprovides' aj seat forsealing or gasket material interposed between the gasket seat and the.slip closure when the latter is in closed fxisition, certain of theclosure elements being formed toipermit ready opening of the containerwhile pro viding a se'atfora carryingbail. 7 To exemplify the'inventionthe drawing discloses a container bodyll toiwhich is applied a bott'om12-secured thereto inany-suitr:

able manner as by a double-seam.: Theupper open endof the container bodywall is bent 5 inwardly into a flange 13' adapted to seamed in with afriction ring annulus. Such an annulus comprises a body 15 slightlylarger" than the diameterof the con tainer body 11 and'at its top isbent'inwardly to provide a horizontal flange 16,,the body 15 Y a beingswelled out or enlarged in diameter into a collar 17 constituting thelower, half of the annulus body 15. This annulus is adapted to beinterengaged with. the container body The upper smaller diametered partof the an- ,nulus body 15 tightly engages theupp'er end of the containerbodywall 11 and provides a vertical wall section 19 the exterior part ofwhich presents a smooth friction wall. r

This friction wall 19 is bent outwardly, ad- V jacent'its bottom edge,into acircular trough section 21 which provides an annular hollow "ordepression 22, the trough section-merging into the top or. horizontalpartof the collar" l 17 A suitable sealing orgasket material 23 apurpose hereinafter. described no s I The outer vertical Wall of thecollar 17 is provided Witlrtivo diametrically opposed openings 2 whichform bail seatsior a handle or bail :25 having inwardly ent horizontalnecks 26 (Fig. 8). adjacent its ends Whiclrterinmate inright angledbends 2'4.

Which lie inside or" the collar section.

This structure provides a strong reinforced upper end for the containerwhich may be conveniently carried by the handle Wall 11 presents verylittle obstruction to the dlscharge of the contents from the containerthus providing a substantially full open] mouth therefor.

closure' which is adapted to be pos t oned over the open end of thecontarnerwvrth its friction Wall 33 engaging'thefraction Wall 19 of thethe depression 22ofthe'annulus asillustrated In this fully assembledposition the container is tightlysealed both by the friction side Wallengagement and'by thezgasket joint. The outer edge 37 of the flange 36'at such timeisspaced' a slight distance abovelthe horizontal top Wall ofthe collar part 17 and;

this space provides an' openchannel 38 for r the insertion of asuitable-prying-ofi tool.

Such a'tool bypressing on. thecollar as a incrum base, lifts upwardlyagainst the cover member by engagement of the flanged edge,member"upwardly and 37 forcing the coverunsealing the container. I 7 VItis thought that the invention and many ofits attendant advantages willbe understood from the foregoing description, and it wlll rbeapparentthat variouschanges'may be' made in the form, construction and arrange.nientof the parts Without departing from the W spirit and soope'oi? their'vention or sacrificing all otits material,advantages, the formliere'inbefore described bein mere-l "a )16- 0d", inner edge in a'doubleseam arranged ithin thebody and having its outer part arranged outsideof the -seamed part o'f-the body to fer'red embodimentfthereof.
